What causes Mercury pollution?

Mercury pollution is primarily caused by industrial activities, such as coal combustion, mining, and waste incineration, which release mercury into the atmosphere. Once airborne, mercury can settle in water bodies, where it can convert to methylmercury, a highly toxic form that accumulates in fish and aquatic organisms. Other sources include artisanal gold mining and the improper disposal of products containing mercury, such as thermometers and batteries. These activities contribute to environmental contamination and pose significant health risks to humans and wildlife.
